Abstract: The invention relates to a method for producing ethylene/vinyl acetate copolymers in which a mixture comprised of ethylene and vinyl acetate is continuously polymerized in the presence of radical polymerization initiators and optional molecular weight modifiers in a cooled tubular reactor at a pressure ranging from 1000 to 3500 bar. The polymerization initiator is charged at the beginning and at a number of positions along the tubular reactor, and the temperature changes in the reaction mixture range no more than 20oC between the first maximum temperature and the last charging of the polymerization initiator along the tubular reactor.
